Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
62 words
An apparatus for collection of macrophage from the peritoneal cavity of a vertebrate including, container means consisting essentially of membrane means, completely enclosing therein an interior volume, for excluding tissue growth into said interior volume and for permitting permeation of macrophage through said membrane means into said interior volume, and cell supporting means filling at least a portion of said interior volume.
Claim 2
Independent Claim
62 words
An apparatus for collection of macrophage from the peritoneal cavity of a vertebrate including, container means consisting essentially of membrane means, completely enclosing therein an interior volume, for excluding tissue growth into said interior volume and for permitting permeation of macrophage through said membrane means into said interior volume, and cell supporting means filling at least a portion of said interior volume.
Claim 3
Independent Claim
115 words
An apparatus for collection of macrophage from the peritoneal cavity of a vertebrate including: container means including: a housing of a material which is impermeable to tissue ingrowth and defining at least one aperture; membrane means, sealing fluid tight said at least one aperture whereby said housing and membrane means cooperate to completely enclose therein an interior volume, for excluding tissue growth through said at least one aperture into said interior volume and for permitting permeation of macrophage through said membrane means into said interior volume, whereby said housing and said membrane means cooperate to exclude tissue growth into said interior volume; and cell supporting means filling at least a portion of said interior volume.
Claim 4
Independent Claim
115 words
An apparatus for collection of macrophage from the peritoneal cavity of a vertebrate including: container means including: a housing of a material which is impermeable to tissue ingrowth and defining at least one aperture; membrane means, sealing fluid tight said at least one aperture whereby said housing and membrane means cooperate to completely enclose therein an interior volume, for excluding tissue growth through said at least one aperture into said interior volume and for permitting permeation of macrophage through said membrane means into said interior volume, whereby said housing and said membrane means cooperate to exclude tissue growth into said interior volume; and cell supporting means filling at least a portion of said interior volume.
Claim 5
Dependent Claim
26 words
The apparatus of claim 2 further including a macrophage permeable interior membrane means within said interior volume, said interior membrane means encompassing said cell supporting means.
Claim 6
Dependent Claim
29 words
The apparatus of either claim 1 or 2 further including a conduit, in fluid tight sealed relationship to said membrane means, and in fluid communication with said interior volume.
Claim 7
Dependent Claim
42 words
The apparatus of claim 4 further including an injection reservoir in fluid tight sealed relationship to said conduit, said injection reservoir having at least a portion thereof puncturable by a hollow needle and self sealing to a track of a hollow needle.
Claim 8
Dependent Claim
31 words
The apparatus of either claim 1 or 2 further including two conduits, each in fluid tight sealed relationship to said membrane means, and each in fluid communication with said interior volume.
Claim 9
Dependent Claim
34 words
The apparatus of claim 6 wherein a first of said conduits is connected to a female adapter, and a second of said conduits is connected to a male adapter interfittable into said female adapter.
Claim 10
Dependent Claim
14 words
The apparatus of either claim 1 or 2 wherein said container means is spherical.
Claim 11
Dependent Claim
72 words
The apparatus of either claim 1 or 2 wherein said container means has, a substantially rectangular outwardly convex front which defines at least one aperture, and is sealingly joined to both: two rectangularly shaped ends; and to two sides each having the shape of an arched band, said two sides each defining at least one aperture, and a substantially rectangular inwardly concave back which is sealingly joined to said ends and sides.
Claim 12
Dependent Claim
63 words
The apparatus of claim 9 further including, a conduit in fluid tight sealed relationship to a central portion of a first of said ends, and flow directing means including two shoulders each tapered from, a relatively large thickness at a portion of each shoulder adjacent a said side, to a relatively small thickness at a portion of each said shoulder adjacent said conduit.
Claim 13
Dependent Claim
19 words
The apparatus of either claim 1 or 2 further including a chemotactic substance combined with said cell supporting means.
Claim 14
Dependent Claim
18 words
The apparatus of either claim 1 or 2 wherein said cell supporting means comprises a plurality of spheres.
Claim 15
Dependent Claim
29 words

Claim 16
Dependent Claim
22 words
The apparatus of either claim 1 or 2 wherein said membrane means defines pore diameters of about 6 to about 20 microns.
Claim 17
Dependent Claim
19 words
The apparatus of claim 14 wherein said membrane means defines pore diameters of about 8 to about 16 microns.
Claim 18
Dependent Claim
16 words
The apparatus of claim 15 wherein said membrane means defines pore diameters of about 8 microns.
Claim 19
Dependent Claim
52 words
A process for collection of macrophage from the peritoneal cavity of a vertebrate comprising, implanting within the peritoneal cavity of a vertebrate the apparatus of claim 1, permitting macrophage to permeate through said membrane means into said interior volume, and removing the permeated macrophage from said interior volume externally of said vertebrate
Claim 20
Dependent Claim
52 words
A process for collection of macrophage from the peritoneal cavity of a vertebrate comprising, implanting within the peritoneal cavity of a vertebrate the apparatus of claim 2, permitting macrophage to permeate through said membrane means into said interior volume, and removing the permeated macrophage from said interior volume externally of said vertebrate.
Claim 21
Dependent Claim
29 words
The process of claim 18 wherein said collector apparatus includes a macrophage permeable interior membrane means within said interior volume, said interior membrane means encompassing said cell supporting means.
Claim 22
Dependent Claim
34 words
The process of either claim 17 or 18 further including, antigen priming the removed permeated macrophage to arm the macrophage against at least one antigen, and introducing the antigen primed macrophage into a vertebrate.
